Ok guys I just bought everything for my super six swap from the local JY. I purcahsed everyting for $50!! Anyways I dont know what the carb cam from though. Its the carter carb, but it doesnt have a tag to tell me what it is. Also what size jets are supposed to be in the slant six? Thanks |

A V8 BBD will have 3 screws holding the top plate on and a /6 BBD only has 1. I never re-jetted the 318 BBD on my car and I gained around 2 mpg over the /6 BBD. |

Usually the V8 carbs have holes in the throttle plates and have a straight tube for the PCV hose while slants usually have a curved tube with no throttle plate holes. Hope I'm correct. |

I can depend on the year for the BBD, I had a 318 BBD off a '74 dart, it had a hole in one throttle plate and a long transfer slot in the other bore. All my super six carbs have no holes in the plates, neither did the BBD off a late 60's 383, oddly enough I also have a BBD off a 1978 318 powered Satellite and it has no throttle plate holes but has the vacuum enrichment circuit you see in '70 Valiant's 318BBD pic.... The variations always are patterned after the options on the car, emmisions and destination of the car (usually Federal, Cali, export, and other states packages...) It's enough to bake a clerk trying to get a rebuild kit for a carb you have no tag for... -D.Idiot |

I must have gotten an older one. mine doesnt have any holes, and it doesnt have the plate with the one or three screws. Mine has the accelerator pump right there. I think It might be off a 273 or something like that. I think I will try it out, but I doubt it will pass emissions. The guy threw it in with the manifold and stuff for no extra charge, so if I have to go get another one its no big deal. Thanks for the help guys, and wish me luck |

I just sold a super six last week and that one had the hole in the choke plate. |

I just checked out the carb I pulled from a 318 and put on my /6 it only has 1 screw holding the top plate on. D'ho!! I guess my way of telling them appart is flawed! |

The only real good way to tell the differance is to meaure the opening for the venturi. The V8 BBDs will be larger. The other way is that the choke lever is differant for a V8 and \6. The V8 BBD will not hook up to the \6 choke rod correctly. Another is if the carb is old enough it will only have a pcv and vacuum advance tubes. This will differantly be a V8 BBD. These guys claim to have jets and metering rods for the BBD: http://www.carbs.net That 383 BBD, what is the size of the throttle blades and does it use the the regular BBD bolt pattern? |

I no longer have that one, it sold a while back, I have one off a 440 Dump Truck engine that is a Carter BBD but is "Industrial" looking, THe 383 version looked like the 318 version, but the throttle plates are a smidge bigger and it uses the same flange as the Holley 2210, and Holley 2245 (so fits a 360,361,383,400...not LA blocks...) -D.Idiot |

Hold up a sec-I thought all 2 bbl big blocks and 360's got the bigger non-bbd carburetor. The name of that carburetor escapes me at the moment. I've never even heard of a 383 or 440 with a bbd until now. My '67 fury had the bigger 2 barrel I'm talking about on its 383. It looked nothing like a bbd, and the air cleaner mounting surface was considerably bigger than a bbd. What gives? |

The slant 6/318 BBD is the BBD 1 1/4", the 360/383 BBD is the BBD 1 1/2". There was also a Holley 2200 series 2 barrel used on some 383s. Cecil |

I thought that big 2 barrel wasn't a bbd. It was definitely not a holley though. |

It might have been a stromberg. Chrysler used them too. |

BBD 1 1/4 and 1 1/2 is what Mopar calls them in the service manuals. Most of the fuel circuits are in the same place and, other than size, look the same. Cecil |
